Description:

FIELD OF THE INVENTION

The present invention relates generally to the field of anti-infective, anti-proliferative, anti-inflammatory, and prokinetic agents, and more particularly, the invention relates to a family of bifunctional heterocyclic compounds useful as such an agent.

BACKGROUND

The evolution of strains of cells or organisms resistant to currently effective therapeutic agents is an ongoing medical problem. For example, the development of cancerous cells resistant to chemotherapeutic drugs has long been recognized as a problem in the oncology field. Once resistant cells develop, the therapeutic regime, in order to remain effective, must be modified to introduce other chemotherapeutic agents. Another example of this resistance problem is the development of strains of microbial, fungal, parasitic and viral pathogens resistant to one or more anti-infective agents. As a result, there is still a need for new anti-proliferative and anti-infective agents that are effective against strains of cells or organisms that have developed resistance to currently available agents.

In the field of anti-infective agents, a variety of different antibiotics have been developed and approved for use in humans over the years. An oxazolidinone ring containing antibiotic known as linezolid (see, compound 1), available under the trade name Zyvox®, has been approved for use as an anti-bacterial agent active against Gram-positive organisms. Unfortunately, linezolid resistant strains of organisms are already being reported (Tsiodras et al. (2001) LANCET 358: 207; Gonzales et al. (2001) LANCET 357: 1179; Zurenko et al. (1999) PROCEEDINGS OF THE 39TH ANNUAL INTERSCIENCE CONFERENCE ON ANTIBACTERIAL AGENTS AND CHEMOTHERAPY (ICAAC); San Francisco, Calif., USA, September 26-29).

Because linezolid is both a clinically effective and commercially significant anti-microbial agent, investigators have been working to develop other effective linezolid derivatives. Research has indicated that the oxazolidinone ring is important for linezolid activity. The literature commonly describes molecules having small groups substituted at the C-5 of the oxazolidinone ring, and early structure-activity relationships suggested that compounds with, larger groups at the C-5 position were less active as anti-bacterial agents. As a consequence, it is believed that, in general, investigators have been reluctant to place large substituents at the C-5 position of oxazolidinone rings in anti-microbial agents.

International patent publication no. WO 01/81350 discloses a series of C-5 substituted oxazolidinones (see, general structure 2) where the acetamido group of linezolid was replaced, for example, with an optionally substituted N-linked 5-membered heteroaryl ring or an N-linked 6-membered heteroaryl ring. The 5-membered heteroaryl ring may contain either (i) one to three further nitrogen heteroatoms, or (ii) a further heteroatom selected from O and S together with an optional further nitrogen heteroatom; wherein the ring is optionally substituted on a C-atom by an oxo or thioxo group; and/or is optionally substituted on a C-atom by one or two C1-4 alkyl groups; and/or on an available nitrogen atom (provided that the ring is not thereby quaternized) by C1-4 groups. The N-linked 6-membered heteroaryl ring may contain up to three nitrogen heteroatoms in total, wherein the ring is substituted on a suitable C-atom by oxo or thioxo groups, and optionally substituted on any available C-atom by one or two C1-4 alkyl groups.

In addition, International patent publication nos. WO 99/64416 and WO 00/21960 also disclose a series of 5-substituted oxazolidiniones (see, general structure 3). In particular, WO 99/64416 discloses compounds having the general structure 3, where X is —O— or —S— and HET is a C-linked 6-membered heteroaryl ring containing 1 or 2 nitrogen atoms. WO 00/21960 discloses compounds having the general structure 3, where X is —N(H)— and HET is a C-linked 5-membered heteroaryl ring containing 2 to 4 heteroatoms independently selected from N, O and S.

European Patent no. 0 097 469 B1 discloses intermediates of compound 4 which are useful in the synthesis of triazole anti-fungal agents of general structure 5. The intermediates may contain a disubstituted C-5 atom in the oxazolidinone ring, and the nitrogen atom of the oxazolidinone ring is a secondary amine.

Gregory and coworkers disclose the synthesis of a variety of oxazolidinone containing antibacterial agents (Gregory et al. (1989) J. MED. CHEM. 32: 1673-1681). Compound 6, a C-5 substituted five-membered heteroaryl derivative, was inactive as an antibacterial agent. This observation appears to be consistent with other oxazolidinone containing compounds that have the opposite stereochemical configuration at C-5 relative to that found in linezolid.

Oxazolidinone compounds similar to those of compound 8 have been formed via decomposition of substituted nitrosoureas 7 and have been useful as anticancer agents (Mulcahy et al. (1989) EUR J. CLIN. ONCOL. 5: 1099-1104; Carmiati et al. (1989) BIOCHEM. PHARMACOL. 38: 2253-2258).

The salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or separately by reacting the free base function with a suitable organic acid. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids (such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid), or with organic acids (such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid), or by using other methods used in the art (such as ion exchange). Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.

The term “pharmaceutically acceptable ester” refers to esters that hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Suitable ester groups include, for example, those derived from pharmaceutically acceptable aliphatic carboxylic acids, particularly alkanoic, alkenoic, cycloalkanoic and alkanedioic acids, in which each alkyl or alkenyl moiety advantageously has not more than 6 carbon atoms. Other suitable ester groups include, for example, those derived from pharmaceutically acceptable alcohols, such as stright-chain or branched aliphatic alcohols, benzylic alcohols, and amino-alcohols. Examples of particular esters include formates, acetates, propionates, butyrates, acrylates, ethylsuccinates, and methyl, ethyl, propyl, benzyl, and 2-aminoethyl alcohol esters.

The term “pharmaceutically acceptable prodrugs” refers to those prodrugs of the compounds of the present invention which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals with undue toxicity, irritation, allergic response, and the like, commensurate with a reasonable benefit/risk ratio, and effective for their intended use, as well as the zwitterionic forms, where possible, of the compounds of the invention. The term “prodrug” refers to compounds that are rapidly transformed in vivo to yield the parent compound of the previously formula, for example by hydrolysis in blood. A thorough discussion is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987.

The term “physiologically acceptable cation” refers to common, positively charged species such as (but not limited to) metals such as sodium, potassium, calcium, magnesium, zinc and the like. The cation can also be an organic species such as an amine salt. Non-limiting examples of such amine salts can be the protonated form of methylamine, ethylamine, cyclohexylamine, lysine, N-methylglucamine, diethanolamine, triethanolamine, tris-(hydroxymethyl)aminomethane, piperidine, morpholine, and the like.

The term “electron-withdrawing group” refers to groups well known to those in the art capable of pulling electron density towards the group and away from a source (such as an aromatic ring, an olefin, a carbonyl-like group or a sigma bond between two designated atoms). Examples of such electron-withdrawing groups are, for example, nitro, keto, formyl, acyl, halogens, carboxy, trihaloalkyl, sulfonyl and the like.

Throughout the description, where compositions are described as having, including, or comprising specific components, or where processes are described as having, including, or comprising specific process steps, it is contemplated that compositions of the present invention also consist essentially of, or consist of, the recited components, and that the processes of the present invention also consist essentially of, or consist of, the recited processing steps. Further, it should be understood that the order of steps or order for performing certain actions are immaterial so long as the invention remains operable.

3. Synthesis of the Compounds of the Invention

In another aspect, the invention provides methods for making the compounds of the invention. The following schemes depict some exemplary chemistries available for synthesizing the compounds of the invention. It will be appreciated, however, that the desired compounds may be synthesized using other alternative chemistries known in the art.

Scheme 1 illustrates the synthesis of oxazolidinones substituted at C-5 with 1,2,3-triazolylmethyl derivatives. Isocyanates 14 can react with lithium bromide and glycidyl butyrate at elevated temperature to produce oxazolidinone intermediates of type 15 (Gregory et al. (1989) J. MED. CHEM. 32:1673). Hydrolysis of the resulting butyrate ester of compound 15 produces alcohol 17. Alcohol 17 can also be synthesized from carbamates such as the benzyl carbamate 16. The carbamate nitrogen of compound 16 then is deprotonated, and alkylated with glycidyl butyrate to produce (after in situ hydrolysis of the butyl ester) hydroxymethyl derivative 17. While the R enantiomer depicted throughout Scheme 1 generally is the most biologically useful derivative for antibacterial agents, it is contemplated that compounds derived from either the R or the S enantiomer, or any mixture of R and S enantiomers, may be useful in the practice of the invention.

Alcohols 17 can be converted to useful intermediates such as mesylates 18a (by treatment with methanesulfonyl chloride and triethylamine in an appropriate solvent) and azide 19 (by subsequent displacement of the mesylate by sodium azide in DMF). Azide 19 can also be produced from tosylate 18b (or a brosylate or nosylate), or an alkyl halide of type 18c (made from alcohol 17 via methods known to those skilled in the art). Azide 19 can be heated in the presence of substituted acetylenes 20 to produce C-5 substituted 1,2,3-triazolylmethyl oxazolidinone derivatives of type 21 and 22. It is to be understood that alternative chemical conditions could be employed by those skilled in the art to effect this transformation.

It is understood that unsymmetrical acetylene derivatives can react to produce a mixture of regioisomeric cycloaddition products, represented by 21 and 22, and that the reaction conditions can be adjusted by processes known to those skilled in the art to produce more selectively one regioisomer or the other. For example, Scheme 2 depicts the reaction of mono-substituted acetylene 23 with azide 19 to produce two regioisomeric triazoles, 24 and 25. The major isomer is most often the anti isomer 24 since the reaction leading to this product proceeds at a faster rate. Under certain circumstances, the more sterically disfavored syn isomer is also formed, but at an appreciably diminished rate. The addition of copper(I)iodide is a useful additive for this reaction, and often leads to increased proportions of the major “anti” adduct 24 (Tornoe, C. W. et al. (2002) J. ORG. CHEM. 67: 3057). Increased proportions of the minor isomer 25 may be produced by minor modification of the reaction scheme. Azide 19 can react with the trimethylsilyl substituted acetylene 26 to produce the anti isomer 27 and the syn isomer 28. Desilylation with tetrabutylammonium fluoride can produce triazole 24 and 25, with increased proportions of 25 obtainable from the more abundant precursor triazole 27.

An alternate approach toward the synthesis of some of the compounds of the present invention is shown in Scheme 3. Aromatic halide 29, when activated, can react with the anion derived from treatment of carbamate 33 with an appropriate base to produce 3-aryl substituted oxazolidinone derivatives 31 via nucleophilic aromatic substitution. Suitable bases include, for example, n-BuLi, LiN(Si(CH3)3)2, and NaH. Carbamate 33 can be synthesized by exposure of 32 to carbonyldiimidazole in DMF, followed by in situ silylation of the hydroxymethyl group of the initial product with an appropriate silyl chloride. Desilylation of derivatives of type 31 produces alcohols 17 that can be converted to the targets of the present invention by the processes described within the schemes.

Scheme 4a illustrates the synthesis of some alkynes of type 23 required for the synthesis of some of the compounds of the present invention. Secondary alkyl amines (or cycloalkyl amines) can be alkylated with electrophiles comprised of an alkyne connected by a variable bond or linker to a carbon bearing a leaving group, for example, a halide or sulfonate group (35), to produce alkynes of type 36. The substituted alkynes can be used in cycloaddition reactions with azides to yield triazole-linked target compounds. The amino group undergoing such an alkylation can be derived from amino saccharides, for example (but not limited to), the des-methyl desosamine derivative 37. Desosamine derivative 37 is available from the degradation of erythromycin. Alkylation of 37 with alkynes 35 produces triazole-linked sugar compounds of type 38. The dimethyl amino group of the desosamine sugar of macrolide antibiotics can be monodemethylated to produce the corresponding secondary amine (U.S. Pat. No. 3,725,385, Flynn et al. (1954) J. AM. CHEM. SOC. 76: 3121; Ku et al. (1997) BIOORG. MED. CHEM. LETT. 7: 1203; Stenmark et al. (2000) J. ORG. CHEM. 65: 3875). For example, amine 39 (an intermediate in the synthesis of amino sugar 37), or a suitably protected derivative of 39 such as the per-silylated compound (formed by pre-treatment with bis-trimethylsilylacetamide, hexamethyldisilazane or other agents known in the art) can be alkylated with alkynes of type 35. This alkylation reaction produces intermediates of type 40, that can react with azides of type 19 to yield target compounds.

An alternative route is available for the production of desosamine derivatives 38. Alkynes 40 can be hydrolyzed with strong acid to produce amines 38. It is understood that, given appropriate reaction conditions known to those skilled in the art, any macrolide antibacterial agent (naturally occurring, semi-synthetic or synthesized) is capable of serving as starting material for the processes depicted in Scheme 4a.

Scheme 4b illustrates the synthesis of compounds of the present invention that contain extra keto groups in the alkyl link between the 5-membered heterocyclic ring and the macrolide moiety. Azides 19 can react with propiolate esters to produce the ester-substituted products. (It is to be understood that mixtures of regioisomeric cycloadducts may form in this reaction, however, only the anti adduct is depicted in Scheme 4b.) Hydrolysis of the ester yields the acid, which can be converted using known chemistry (Ramtohul et al. (2000) J. ORG. CHEM. 67: 3169) to the bromoacetyl triazole. Heating this bromoacetyl derivative with 39 (or a suitably protected version of 39) can yield products that contain a keto link with one methylene group between the ketone and the macrolide group. The bromoacetyl intermediate can be converted via lithio-dithiane chemistry, subsequent hydrolysis, and reduction to an alcohol. The tosylate (or halide) of this alcohol can be made, and this electrophile can be used to alkylate 39 to give products with two methylene groups between the ketone and the macrolide group.

Scheme 5 illustrates another method to synthesize regioisomeric triazole-linked derivatives of the invention. Carbon-linked triazole derivatives of type 44 and 45 can be produced by first displacing a leaving group (for example, a sulfonate or a halide) from electrophiles 18a-c, with either lithium acetylide 41a or lithium trimethylsilylacetylide 41b to produce alkynes 42. The cycloaddition reaction of alkynes 42 with appropriate azides 43 can yield regioisomeric triazoles 44 and 45. (It will be understood that alternative chemical conditions could be employed to produce compounds 44 and 45 such as the use of copper(I)iodide instead of heat).

embedded image

A specific example of the utility of the chemistry expressed in Scheme 5 is shown in Scheme 6. Des-methyl erythromycin derivative 39 (or a suitably protected derivative thereof) can be alkylated with a bromoalcohol, and the alcohol function of the product converted to a leaving group such as a tosylate. The tosylate can be displaced with sodium azide to yield azide 46. Cycloadditon of 46 and alkyne 42a can produce final targets of type 47. Alternative alkylsulfonates or halides can be used as the starting material for the synthesis of azide 46 (i.e., different leaving groups). Other macrolide entities can be used in place of the des-methyl erythromycin derivative 39 to produce a variety of alternative products.

embedded image

Another method that can be used to synthesize carbon-linked triazole derivatives of type 47 is illustrated in Scheme 7. Alkyne 42a can react with trimethylsilylazide (or with sodium azide, ammonium chloride and copper(I)iodide, or other conditions known in the art) to produce two possible regioisomeric products, triazoles 48 and 49. Either of these (or the mixture) can be desilylated with n-Bu4NF to produce triazole 50. Des-methyl erythromycin derivative 39 (or an alternate des-methyl amino macrolide derivative) can be converted to tosylate 51 (or another sulfonate or halide electrophile), and then the electrophile can serve to alkylate triazole 50 to produce either the N-1 substituted triazole 47, or the N-2 substituted triazole 53, or a mixture of both. In the event that a mixture is produced, both compounds may be separated from one another. It is contemplated that other macrolides may be transformed by the chemistry of Scheme 7 to produce other compounds of interest.

Scheme 8a illustrates the synthesis of oxazolidinones substituted at C-5 with tetrazolylmethyl derivatives. Azides of type 19 can react with nitrites 54 to produce tetrazoles of type 55 and 56. In a similar fashion to the chemistry described in Scheme 1, this reaction can yield regioisomeric cycloadducts, where the anti isomer often predominates. As an example, des-methyl erythromycin 39 can be alkylated with ω-halo or ω-sulfonate nitrites to yield nitrites 57. These derivatives can react with azides of type 19 to produce target tetrazoles of type 59 and 60. It is to be understood that the R′ group of nitrites 54 may contain the macrolide moiety, or suitable substituted alkyl groups containing an alcohol or protected alcohol that could be converted to a leaving group prior to a final alkylation step with a macrolide amine. Thus, the tetrazoles 55 and 56 could be produced that have as their R′ groups alkyl chains bearing a hydroxy group that can be converted into a sulfonate or halide leaving group prior to alkylation with amines similar to 39 to afford products of type 59 and 60. The hydroxy group may be unmasked from a protected hydroxyl group in the compounds 55 and 56 prior to further conversions as mentioned above to afford targets of type 59 and 60.

embedded image embedded image

Scheme 8b depicts another strategy to synthesize tetrazoles of type 59 and 60. Azides 19 could undergo cycloaddition to functionalized nitrites of type 57a to afford tetrazole intermediates 55a and 56a. If 55a and 56a contain an appropriate electrophilic group such as a halide or sulfonate, it can react directly with macrolide amines of type 39 (or a suitably protected derivative thereof) to yield targets of type 59 and 60. Alternatively, silyloxy-substituted nitriles 57a could be used during the cycloaddition reaction to afford intermediates of type 55a and 56a where X is a silyloxy group. The silylether protecting group could then be removed from 55a and 56a, and the resultant alcohol converted to an appropriate electrophile (Such as a halide or sulfonate) that would then be suitable for alkylation of macrolide amines of type 39 to give the desired targets.

embedded image

It will be understood that if the alkyl group bearing substituent X in 55a and 56a contains a hydroxyl group, the group could be oxidized to an aldehyde by methods well known to those skilled in the art. Such aldehydes could be used to produce targets of type 59 and 60 via the use of reductive amination conditions employed on these aldehydes and macrolide amines similar to amine 39 (or suitably protected variants thereof).

Scheme 9 illustrates one method of synthesizing pyrazole derivatives of the present invention. Known trityl-protected organolithium derivative 61 (Elguero et al. (1997) SYNTHESIS 563) can be alkylated with electrophiles of type 18a-c to produce pyrazoles of type 62. Cleavage of the trityl group can be accomplished using a variety of acidic reagents, for example, trifluoroacetic acid (TFA), to produce pyrazole 63. Alkylation of 63 with a bromoalcohol of appropriate length, followed by tosylation (or alternate sulfonation or halide formation) can produce electrophiles 64. Alkylation of 39 with 64 produces targets of type 65. The lithium anions derived from heterocycles such as 61 may optionally be converted to copper (or other metallic) derivatives to facilitate their displacement reactions with sulfonates and halides. These anions may also be allowed to react with suitably protected macrolides, such as the per-silylated derivative of 51.

Scheme 10 depicts another method of synthesizing pyrazoles of the present invention. Anions 61 can be alkylated with a bifunctional linker of variable length such as an alkyl halide containing a silyloxy derivative. Alternatively an α,ω dihaloalkyl derivative can be used as the alkylating agent, or a mixed halo-sulfonate can be employed for this purpose. The resulting substituted pyrazoles 66 can be converted to the free pyrazoles by TFA cleavage of the triphenylmethyl protecting group. The free pyrazoles can undergo direct alkylation with electrophiles 18a-c in a suitable solvent, for example, dimethylformamide, or can be first converted via deprotonation with a suitable base, for example, sodium hydride or n-butyllithium, to the corresponding anion, if a more reactive nucleophile is required. The resultant pyrazole derivatives 67 can be desilylated and converted to tosylates 68 (if a sulfonate strategy is employed), which can serve as electrophiles for subsequent reaction with macrolide aminosaccharides, for example, amine 39, to produce the resultant target 69.

Another approach to intermediates of type 67 can start with alkylation of the known dianion 70 (Hahn et al. (1991) J. HETEROCYCLIC CHEMISTRY 28: 1189) with an appropriate bifunctional linker to produce compounds related to pyrazole 71, which can subsequently be alkylated (with or without prior deprotonation) with electrophiles 18a-c to produce intermediates 67. The n=1 derivatives in this series can be synthesized by trapment of compound 61 with DMF to produce the corresponding aldehyde, and then reduction to the alcohol. Alternatively, methoxymethyl (MOM) chloride or bromide can serve as the alkylating reagent for 61, and hydrolysis of the trityl and MOM groups of the product would yield 4-hydroxymethyl-1,2-pyrazole. The dianion of this pyrazole can be alkylated on nitrogen to produce an alcohol that serves as the precursor for a n=1 tosylate (or other leaving group).

Scheme 11 shows an alternate approach for synthesizing pyrazole derivatives of type 69. Alkylation of the anion of a β-dicarbonyl system with appropriate electrophiles similar to tosylate 51 can yield (in the specific example of β-dicarbonyl derivative 72a) products of type 73. Treatment of these intermediates with hydrazine can produce pyrazoles of type 74. Direct alkylation of 74 with electrophiles 18a-c can proceed to produce targets 69. Alternatively, the hydroxyl residues of 74 (and other sensitive functional groups of other macrolide derivatives such as intermediates 39 and 51) can be protected with suitable protecting groups (such as those highlighted in Greene, T. W. and Wuts, P. G. M. supra). and the hydrogen atom on the nitrogen atom of the pyrazole derivative deprotonated with a suitable base, for example, sodium hydride or n-butyllithium. The resulting anion can then be alkylated with electrophiles 18a-c, and the resulting product deprotected to produce targets 69. The use of protecting groups well known to those skilled in the art for the macrolide portions of these intermediates may be required for many of the subsequent reactions shown in the schemes below that involve heteroaryl anion alkylations.

Scheme 12 exemplifies a synthesis of imidazoles of the present invention. The known dianion 75 (Katritzky et al. (1989) J. CHEM. SOC. PERKIN TRANS. 1: 1139) can react with electrophiles 18a-c to produce after protic work-up imidazoles of type 76. Direct alkylation of 76 by heating with electrophiles related to 51 in an appropriate organic solvent can yield 1,4-disubstituted imidazoles 77. Alternatively, the imidazole anion formed via deprotonation of the imidazole hydrogen atom of 76 with a suitable base and then alkylation with 51 can also produce 77.

embedded image

Scheme 13 illustrates another synthesis of imidazoles of the present invention. 4-Bromoimidazole can be deprotonated using, for example, sodium hydride or lithium diisopropylamide, or another suitable organic base, to give anion 78 (or the corresponding lithio derivative). Alkylation of 78 with 18a-c can yield bromoimidazole 79 which can then be subjected to metal-halogen exchange and alkylated with 51 (or a suitably protected derivative of 51) to produce isomeric 1,4-disubstituted imidazoles 80.

Scheme 14 depicts chemistry suitable for the synthesis of other target imidazole derivatives. The silylethoxymethyl (SEM) protected imidazole can be lithiated at C-2 (Shapiro et al. (1995) HETEROCYCLES 41: 215) and can react with electrophiles 18a-c to produce imidazole intermediates 82. Lithiation of imidazole intermediates 82 at C-4 of the imidazole, followed by alkylation with electrophiles of type 51 (or a suitably protected version such as the per-silylated derivative), and then deprotection of the SEM can produce imidazoles 83.

Scheme 15 shows how tosylmethyl isocyanide can be used to make imidazoles of the present invention (Vanelle et al. (2000) EUR. J. MED. CHEM. 35: 157; Horne et al. (1994) HETEROCYCLES 39: 139). Alcohols 17 can be oxidized to produce aldehydes 85 using an appropriate agent such as the Dess-Martin periodinane, or oxalyl chloride/dimethylsulfoxide/triethylamine (Swern oxidation). A variety of chromium complexes can also be used for this oxidation, including, for example, pyridinium dichromate (PDC), pyridinium chlorochromate (PCC), chromium trioxide, and tetrapropylammonium perruthenate. Wittig homologation of 85 can provide aldehyde 86, which can then be converted by tosylmethyl isocyanide to produce intermediate 87. The reaction of 87 with amines 89 (formed via alkylation of amines 39 with bromoalkyl phthalimides 88 followed by hydrazine cleavage, or reduction of azides 46) can produce imidazoles 77.

Scheme 16 delineates how 1,3 thiazole and 1,3 oxazole derivatives of the present invention can be synthesized. Known dibromo thiazoles and oxazoles 90a and 90b can be selectively metallated at C-2 and alkylated with electrophiles 18a-c to produce intermediates 91a and 91b (Pinkerton et al. (1972) J. HETEROCYCLIC CHEMISTRY 9: 67). Transmetallation with zinc chloride can be employed in the case of the oxazole anion if the anion displays any tendency to ring open prior to its reaction with certain electrophiles. The bromo azoles 91 can be metallated to form the corresponding anion which can undergo alkylation with sulfonates 51 (or the related halides) to produce the final targets 92. Reordering of the sequence of electrophiles in this process permits access to the isomeric thiazoles and oxazoles 93.

Scheme 17 shows the synthesis of 2,5 disubstituted furan and thiophene derivatives of the invention. Commercially available dibromofuran 94a and dibromothiophene 94b can be monolithiated (Cherioux et al. (2001) ADVANCED FUNCTIONAL MATERIALS 11: 305) and alkylated with electrophiles 18a-c. The monobromo intermediates obtained from this reaction can be lithiated again and then alkylated with electrophiles of type 51 (or a protected version of 51) to produce the final targets 95.

Scheme 18 depicts the synthesis of 2,4 disubstituted furan and thiophene derivatives of the invention. Commercially available furan aldehyde 96a, and the known thiophene aldehyde 96b, can be reduced to the corresponding alcohols and the resulting alcohols converted to a leaving group such as tosylates 97. Alternate sulfonates and halides can be synthesized and used in this fashion. The tosylates 97 can alkylate amine 39 (or a protected version thereof), and the heteroaryl bromide can be converted to a suitable organometallic agent (by reagents such as n-BuLi, or i-Pr2Mg/CuCN). This intermediate organometallic agent can be alkylated with electrophiles 18a-c to produce targets of type 98 where n=1. As the scheme shows, a reordering of steps can be employed involving reduction, silylation, lithiation and then initial alkylation with 18a-c. Desilylation of the alkylation product, followed by tosylation of the alcohol, provides an intermediate that can then be alkylated with amine 39 to produce targets 98. Simple homologation protocols, using the reagents depicted in Scheme 18 or others known to those skilled in the art, can convert the aldehydes 96 to longer chain tosylates such as 99 and 100. The use of these tosylates in the alkylation with 39, and subsequent metal-halogen exchange and alkylation with 18a-c, can yield compounds of type 98 where n=2 and 3. It will be appreciated that longer chain tosylates can be produced using chemistries similar to that depicted in Scheme 18, and that other bifunctional linkers can be used to produce compounds of type 98.

Chemistries similar to that employed above in Scheme 18 can convert known thiophene aldehyde 101 (Eras et al. (1984) J. HETEROCYCLIC CHEMISTRY 21: 215) to produce products of type 104 (Scheme 19). The known acid 102 (Wang et al. (1996) TETRAHEDRON 52: 12137) can be converted to aldehyde 103 by reduction with, for example, borane or lithium aluminum hydride, followed by oxidation of the resultant hydroxymethyl intermediate with, for example, PDC, PCC, or another suitable reagent. Aldehyde 103 can then be converted to produce compounds of type 104.

Scheme 20 illustrates the synthesis of 2,5 disubstituted pyrroles of the invention. The BOC-protected dibromopyrrole 105 can be lithiated and alkylated sequentially (Chen et al. (1987) TETRAHEDRON LETT. 28: 6025; Chen et al. (1992) ORG. SYNTH. 70: 151; and Martina et al. (1991) SYNTHESIS 613), and allowed to react with electrophiles 18a-c and 51 (or a suitably protected analogue of 51) to produce, after final BOC deprotection with TFA, disubstituted pyrroles of type 106.

Scheme 21 shows the synthesis of 2,4 disubstituted pyrroles of the invention. Commercially available pyrrole ester 107 can be protected with a suitable protecting group, for example, the BOC group, and the ester function hydrolyzed to the corresponding acid. The resulting acid can then be reduced to the alcohol using, for example, borane to yield an alcohol that can be converted to tosylate 108. Amine 39 (or a suitably protected version of 39, formed for example by silylation of the hydroxyl groups with bis-trimethylsilylacetamide or another silylating reagent) can be alkylated with tosylate 108 to produce an intermediate bromopyrrole. The bromopyrrole can then be converted to an organometallic reagent that can then react with electrophiles 18a-c. The resulting product can then be deprotected with TFA to produce pyrroles 109. The alcohol formed after borane reduction of the acid derived from 107 can then be homologated to tosylates 110 and 111 by chemistries similar to that shown below in Scheme 23. The use of these tosylates in the alkylation strategy can produce target pyrroles of type 109 where n=2 and 3.

An alternative approach is to protect the alcohol functions prior to tosylation, and perform the alkylation of the organometallic derived from the halopyrrole with 18a-c first. For example, silyloxy derivative 112 can be produced from 107, and the organometallic derivative derived from it alkylated with 18a-c to yield silyl ethers 113. Subsequent desilylation and conversion to tosylates 114 provides an electrophile that can be used in the alkylation reaction with 39. A final BOC cleavage can then give pyrroles 109. It is understood that the alcohol precursor of 112 can be homologated, using chemistries similar to that shown below in Scheme 23 and other schemes) to other alkanols that can be tosylated for further reactions with amine 39 (or related macrolide derived amines). Furthermore, the alcohol derived from silyl cleavage of 113 can serve as the starting material for this type of homologation efforts to produce the alkyl tosylates (or halides) required for making targets 109 where n is variable.

Scheme 22 shows the synthesis of isomeric 2,4 disubstituted pyrroles of the invention. Commercially available pyrrole acid 115 can be protected as the BOC derivative, and the acid function reduced to an alcohol, which can then be protected to produce the silyl ether 116. Deprotonation of 116 with n-butyllithium can occur at the 5 position of the pyrrole ring, and this anion (or that derived from transmetallation with an appropriate metal) can be alkylated with electrophiles 18a-c to produce pyrrole 117. Desilylation of 117, followed by tosylation, alkylation with amine 39, and TFA deprotection of the BOC group can yield pyrroles 119.

embedded image

Scheme 23 illustrates the synthesis of longer chain tosylates of type 123 and 126 used to alkylate amines of type 39 to produce pyrroles 119. The alcohol 120 derived from protection of 115 followed by borane reduction can be oxidized to aldehyde 124. The Wittig reaction of aldehyde 124 with methoxymethyl triphenylphosphorane is followed by an acid hydrolysis step to produce the homologated aldehyde 121. Reduction and silyl protection can yield 122, which can then be deprotonated, alkylated and then converted to tosylate 123. Aldehyde 124 can undergo a Wittig reaction with carbomethoxymethyl triphenylphosphorane. The Wittig product then is reduced to an alkanol that can then be silylated to produce 125. Conversion of 125 to pyrroles 119 can then occur using the same chemistry employed to provide 119 from 122.

embedded image

Scheme 24 shows the synthesis of 1,3 disubstituted pyrroles of the present invention. The BOC group of 116 can be cleaved to produce free pyrrole 127. Alkylation of 127 (in a suitable organic solvent such as DMF) with 18a-c can produce intermediate 128. The dianion of 3-hydroxymethylpyrrole can also be suitable for alkylation with 18a-c to produce the free hydroxy derivative of silyl ether 128. Conversion of the siloxy group to the corresponding tosylate, followed by alkylation with amines of type 39 can generate the target N-substituted pyrroles 129 (where n=1). In a similar fashion, the BOC pyrroles 122 and 125 can be converted to the tosylates 130 and 131. These tosylates can be used to produce pyrroles of type 129 (where n=2 and 3). It is understood that longer chain alkyl tosylates (and halides) can be produced that can undergo this chemistry to produce pyrroles 129 where n is >3.

Scheme 25 illustrates the use of hydantoin-like groups as the 5-membered heterocyclic linker between the G groups and the R1 moieties of the present invention. Electrophiles of type 18a-c can alkylate anions derived from hydantoins to produce compounds of the present invention. For example, 3-substituted hydantoins of type 132 can be purchased and treated with an appropriate base to generate the corresponding imide anion. The resulting anions can be alkylated with electrophiles similar (but not limited) to intermediates 18a-c to produce hydantoin derivatives 134. Alternatively, 1-substituted hydantoins of type 133 can be purchased or prepared, and treated with base and electrophile to yield isomeric hydantoin derivatives 135. It is understood that such hydantoins can have, for example, at optional locations, thiocarbonyl functionalities in place of the illustrated carbonyl groups. Such compounds can be prepared by treatment of the oxy-hydantoins with Lawesson's reagent, elemental sulfur, phosphorus pentasulfide, and other reagents commonly used in the art to perform this transformation.

Alternatively, such thiohydantoins can be synthesized selectively by sequential synthetic steps known in the art. The R′ group of 132 and 133 may represent a protecting group function, for example, benzyl, alkoxybenzyl, benzyloxycarbonyl, t-butoxycarbonyl, that is compatible with the alkylation step. Such a protecting group can subsequently be removed from products 134 and 135, yielding products where the R′ group is a hydrogen atom. These intermediates can be used to produce various target molecules by their treatment with base and then subsequent exposure to appropriate electrophiles.

A more specific example of the synthesis of hydantoin derivatives of the present invention is depicted in Scheme 26. Hydantoin 136 can be treated with a mild organic base, for example, sodium hydride, potassium tertiary-butoxide, cesium, sodium, or potassium carbonate, to produce the N-1 substituted intermediate 137. Deprotonation of 137 with a base, for example, sodium hydride, n-butyllithium, lithium bis-trimethylsilylamide or lithium diisopropylamide, followed by alkylation with 51 (or a suitably protected derivative of 51) can yield hydantoin targets of type 138. The isomeric hydantoin derivatives of type 141 can be synthesized from 136 by initial p-methoxybenzyl (PMB) protection of the N-1 position, followed by alkylation at N-3 with 18a-c and subsequent deprotection of the PMB group with either 2,3-dichloro-3,4-dicyano-benzoquinone (DDQ) or hydrogenation will yield hydantoin intermediates-140. Subsequent alkylation of 140 with 51 can give compounds 141. Another route to produce intermediates 140 is by formation of the dianion of hydantoin 136. One equivalent of a weak base can deprotonate the N-1 position of 136. The addition of another equivalent of a strong base, for example, n-butyllithium, to the initial anion can deprotonate it again, this time at N-3. Alkylation can occur at the more reactive position (N-3) to again produce hydantoins 140.

Scheme 27 illustrates how isoxazolidinone derivatives of type 515 of the present invention can be synthesized. Macrolide 171 (or any other macrolide amine) can be converted to alkyl azide 510 (where n≧2) via use of an appropriate alkyl halide or sulfonate electrophile of type 511. A variety of isoxazolidinone derivatives of type 512 (for syntheses of these types of derivatives see US Patent Application 20020094984) can be alkylated with propargyl electrophiles of type 513 to yield alkynes of type 514. The cycloaddition of azides 510 and alkynes 514 yields target isoxazolidinone derivatives 515. It is to be understood that alternative macrolides and isoxazolidinone derivatives can be used in this chemistry, and alternate chain lengths of the various electophiles can be utilized to produce other compounds of the present invention. It is intended that such alternate targets are within the scope of the present invention.

4. Characterization of Compounds of the Invention

Compounds designed, selected and/or optimized by methods described above, once produced, may be characterized using a variety of assays known to those skilled in the art to determine whether the compounds have biological activity. For example, the molecules may be characterized by conventional assays, including but not limited to those assays described below, to determine whether they have a predicted activity, binding activity and/or binding specificity.

Furthermore, high-throughput screening may be used to speed up analysis using such assays. As a result, it may be possible to rapidly screen the molecules described herein for activity, for example, as anti-cancer, anti-bacterial, anti-fungal, anti-parasitic or anti-viral agents. Also, it may be possible to assay how the compounds interact with a ribosome or ribosomal subunit and/or are effective as modulators (for example, inhibitors) of protein synthesis using techniques known in the art. General methodologies for performing high-throughput screening are described, for example, in Devlin (1998) High Throughput Screening, Marcel Dekker; and U.S. Pat. No. 5,763,263. High-throughput assays can use one or more different assay techniques including, but not limited to, those described below.

(1) Surface Binding Studies. A variety of binding assays may be useful in screening new molecules for their binding activity. One approach includes surface plasmon resonance (SPR) which can be used to evaluate the binding properties molecules of interest with respect to a ribosome, ribosomal subunit or a fragment thereof.

SPR methodologies measure the interaction between two or more macromolecules in real-time through the generation of a quantum-mechanical surface plasmon. One device, (BIAcore Biosensor RTM from Pharmacia Biosensor, Piscatawy, N.J.) provides a focused beam of polychromatic light to the interface between a gold film (provided as a disposable biosensor “chip”) and a buffer compartment that can be regulated by the user. A 100 nm thick “hydrogel” composed of carboxylated dextran which provides a matrix for the covalent immobilization of analytes of interest is attached to the gold film. When the focused light interacts with the free electron cloud of the gold film, plasmon resonance is enhanced. The resulting reflected light is spectrally depleted in wavelengths that optimally evolved the resonance. By separating the reflected polychromatic light into its component wavelengths (by means of a prism), and determining the frequencies which are depleted, the BIAcore establishes an optical interface which accurately reports the behavior of the generated surface plasmon resonance. When designed as above, the plasmon resonance (and thus the depletion spectrum) is sensitive to mass in the evanescent field (which corresponds roughly to the thickness of the hydrogel). If one component of an interacting pair is immobilized to the hydrogel, and the interacting partner is provided through the buffer compartment, the interaction between the two components can be measured in real time based on the accumulation of mass in the evanescent field and its corresponding effects of the plasmon resonance as measured by the depletion spectrum. This system permits rapid and sensitive real-time measurement of the molecular interactions without the need to label either component.

(2) Fluorescence Polarization. Fluorescence polarization (FP) is a measurement technique that can readily be applied to protein-protein, protein-ligand, or RNA-ligand interactions in order to derive IC50s and Kds of the association reaction between two molecules. In this technique one of the molecules of interest is conjugated with a fluorophore. This is generally the smaller molecule in the system (in this case, the compound of interest). The sample mixture, containing both the ligand-probe conjugate and the ribosome, ribosomal subunit or fragment thereof, is excited with vertically polarized light. Light is absorbed by the probe fluorophores, and re-emitted a short time later. The degree of polarization of the emitted light is measured. Polarization of the emitted light is dependent on several factors, but most importantly on viscosity of the solution and on the apparent molecular weight of the fluorophore. With proper controls, changes in the degree of polarization of the emitted light depends only on changes in the apparent molecular weight of the fluorophore, which in-turn depends on whether the probe-ligand conjugate is free in solution, or is bound to a receptor. Binding assays based on FP have a number of important advantages, including the measurement of IC50s and Kds under true homogenous equilibrium conditions, speed of analysis and amenity to automation, and ability to screen in cloudy suspensions and colored solutions.

(3) Protein Synthesis. It is contemplated that, in addition to characterization by the foregoing biochemical assays, the compound of interest may also be characterized as a modulator (for example, an inhibitor of protein synthesis) of the functional activity of the ribosome or ribosomal subunit.

Furthermore, more specific protein synthesis inhibition assays may be performed by administering the compound to a whole organism, tissue, organ, organelle, cell, a cellular or subcellular extract, or a purified ribosome preparation and observing its pharmacological and inhibitory properties by determining, for example, its inhibition constant (IC50) for inhibiting protein synthesis. Incorporation of 3H leucine or 35S methionine, or similar experiments can be performed to investigate protein synthesis activity. A change in the amount or the rate of protein synthesis in the cell in the presence of a molecule of interest indicates that the molecule is a modulator of protein synthesis. A decrease in the rate or the amount of protein synthesis indicates that the molecule is a inhibitor of protein synthesis.

Furthermore, the compounds may be assayed for anti-proliferative or anti-infective properties on a cellular level. For example, where the target organism is a micro-organism, the activity of compounds of interest may be assayed by growing the micro-organisms of interest in media either containing or lacking the compound. Growth inhibition may be indicative that the molecule may be acting as a protein synthesis inhibitor. More specifically, the activity of the compounds of interest against bacterial pathogens may be demonstrated by the ability of the compound to inhibit growth of defined strains of human pathogens. For this purpose, a panel of bacterial strains can be assembled to include a variety of target pathogenic species, some containing resistance mechanisms that have been characterized. Use of such a panel of organisms permits the determination of structure-activity relationships not only in regards to potency and spectrum, but also with a view to obviating resistance mechanisms. The assays may be performed in microtiter trays according to conventional methodologies as published by The National Committee for Clinical Laboratory Standards (NCCLS) guidelines (NCCLS. M7-A5-Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria That Grow Aerobically; Approved Standard-Fifth Edition. NCCLS Document M100-S12/M7 (ISBN 1-56238-394-9).

The compounds may be assayed for anti-inflammatory properties on a cellular level, for example, to determine the inhibition of cytokine production. Further, the compounds may be assessed for calcium flux in CHO cells expressing the human motilin receptor or in animal models for prokinetic behavior such as the rabbit duodenum strip model known to display contractility when a motilin agonist is applied.

5. Formulation and Administration

The compounds of the invention may be useful in the prevention or treatment of a variety of human or other animal disorders, including for example, bacterial infection, fungal infections, viral infections, parasitic diseases, and cancer. It is contemplated that, once identified, the active molecules of the invention may be incorporated into any suitable carrier prior to use. The dose of active molecule, mode of administration and use of suitable carrier will depend upon the intended recipient and target organism. The formulations, both for veterinary and for human medical use, of compounds according to the present invention typically include such compounds in association with a pharmaceutically acceptable carrier.

The carrier(s) should be “acceptable” in the sense of being compatible with the other ingredients of the formulations and not deleterious to the recipient. Pharmaceutically acceptable carriers, in this regard, are intended to include any and all solvents, dispersion media, coatings, anti-bacterial and anti-fungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. The use of such media and agents for pharmaceutically active substances is known in the art. Except insofar as any conventional media or agent is incompatible with the active compound, use thereof in the compositions is contemplated. Supplementary active compounds (identified or designed according to the invention and/or known in the art) also can be incorporated into the compositions. The formulations may conveniently be presented in dosage unit form and may be prepared by any of the methods well known in the art of pharmacy/microbiology. In general, some formulations are prepared by bringing the compound into association with a liquid carrier or a finely divided solid carrier or both, and then, if necessary, shaping the product into the desired formulation.

A pharmaceutical composition of the invention should be formulated to be compatible with its intended route of administration. Examples of routes of administration include oral or parenteral, for example, intravenous, intradermal, inhalation, transdermal (topical), transmucosal, and rectal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide.

Useful solutions for oral or parenteral administration can be prepared by any of the methods well known in the pharmaceutical art, described, for example, in Remington's Pharmaceutical Sciences, (Gennaro, A., ed.), Mack Pub., (1990). Formulations for parenteral administration can also include glycocholate for buccal administration, methoxysalicylate for rectal administration, or citric acid for vaginal administration. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic. Suppositories for rectal administration also can be prepared by mixing the drug with a non-irritating excipient such as cocoa butter, other glycerides, or other compositions which are solid at room temperature and liquid at body temperatures. Formulations also can include, for example, polyalkylene glycols such as polyethylene glycol, oils of vegetable origin, hydrogenated naphthalenes, and the like. Formulations for direct administration can include glycerol and other compositions of high viscosity. Other potentially useful parenteral carriers for these drugs include ethylene-vinyl acetate copolymer particles, osmotic pumps, implantable infusion systems, and liposomes. Formulations for inhalation administration can contain as excipients, for example, lactose, or can be aqueous solutions containing, for example, polyoxyethylene-9-lauryl ether, glycocholate and deoxycholate, or oily solutions for administration in the form of nasal drops, or as a gel to be applied intranasally. Retention enemas also can be used for rectal delivery.

Formulations of the present invention suitable for oral administration may be in the form of: discrete units such as capsules, gelatin capsules, sachets, tablets, troches, or lozenges, each containing a predetermined amount of the drug; a powder or granular composition; a solution or a suspension in an aqueous liquid or non-aqueous liquid; or an oil-in-water emulsion or a water-in-oil emulsion. The drug may also be administered in the form of a bolus, electuary or paste. A tablet may be made by compressing or moulding the drug optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing, in a suitable machine, the drug in a free-flowing form such as a powder or granules, optionally mixed by a binder, lubricant, inert diluent, surface active or dispersing agent. Moulded tablets may be made by moulding, in a suitable machine, a mixture of the powdered drug and suitable carrier moistened with an inert liquid diluent.

Oral compositions generally include an inert diluent or an edible carrier. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients. Oral compositions prepared using a fluid carrier for use as a mouthwash include the compound in the fluid carrier and are applied orally and swished and expectorated or swallowed. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose; a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor ELTM (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). It should be stable under the conditions of manufacture and storage and should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyetheylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.

Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filter sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation include vacuum drying and freeze-drying which yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Formulations suitable for intra-articular administration may be in the form of a sterile aqueous preparation of the drug which may be in microcrystalline form, for example, in the form of an aqueous microcrystalline suspension. Liposomal formulations or biodegradable polymer systems may also be used to present the drug for both intra-articular and ophthalmic administration.

Formulations suitable for topical administration, including eye treatment, include liquid or semi-liquid preparations such as liniments, lotions, gels, applicants, oil-in-water or water-in-oil emulsions such as creams, ointments or pastes; or solutions or suspensions such as drops. Formulations for topical administration to the skin surface can be prepared by dispersing the drug with a dermatologically acceptable carrier such as a lotion, cream, ointment or soap. Particularly useful are carriers capable of forming a film or layer over the skin to localize application and inhibit removal. For topical administration to internal tissue surfaces, the agent can be dispersed in a liquid tissue adhesive or other substance known to enhance adsorption to a tissue surface. For example, hydroxypropylcellulose or fibrinogen/thrombin solutions can be used to advantage. Alternatively, tissue-coating solutions, such as pectin-containing formulations can be used.

For inhalation treatments, inhalation of powder (self-propelling or spray formulations) dispensed with a spray can, a nebulizer, or an atomizer can be used. Such formulations can be in the form of a fine powder for pulmonary administration from a powder inhalation device or self-propelling powder-dispensing formulations. In the case of self-propelling solution and spray formulations, the effect may be achieved either by choice of a valve having the desired spray characteristics (i.e., being capable of producing a spray having the desired particle size) or by incorporating the active ingredient as a suspended powder in controlled particle size. For administration by inhalation, the compounds also can be delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.

Systemic administration also can be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants generally are known in the art, and include, for example, for transmucosal administration, detergents and bile salts. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds typically are formulated into ointments, salves, gels, or creams as generally known in the art.

The active compounds may be prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. Liposomal suspensions can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811.

Oral or parenteral compositions can be formulated in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active compound and the particular therapeutic effect to be achieved, and the limitations inherent in the art of compounding such an active compound for the treatment of individuals. Furthermore, administration can be by periodic injections of a bolus, or can be made more continuous by intravenous, intramuscular or intraperitoneal administration from an external reservoir (e.g., an intrvenous bag).

Where adhesion to a tissue surface is desired the composition can include the drug dispersed in a fibrinogen-thrombin composition or other bioadhesive. The compound then can be painted, sprayed or otherwise applied to the desired tissue surface. Alternatively, the drugs can be formulated for parenteral or oral administration to humans or other mammals, for example, in therapeutically effective amounts, e.g., amounts which provide appropriate concentrations of the drug to target tissue for a time sufficient to induce the desired effect.

Where the active compound is to be used as part of a transplant procedure, it can be provided to the living tissue or organ to be transplanted prior to removal of tissue or organ from the donor. The compound can be provided to the donor host. Alternatively or, in addition, once removed from the donor, the organ or living tissue can be placed in a preservation solution containing the active compound. In all cases, the active compound can be administered directly to the desired tissue, as by injection to the tissue, or it can be provided systemically, either by oral or parenteral administration, using any of the methods and formulations described herein and/or known in the art. Where the drug comprises part of a tissue or organ preservation solution, any commercially available preservation solution can be used to advantage. For example, useful solutions known in the art include Collins solution, Wisconsin solution, Belzer solution, Eurocollins solution and lactated Ringer's solution.

The active compound may be administered directly to a tissue locus by applying the compound to a medical device that is placed in contact with the tissue. For example, an active compound may be applied to a stent at the site of vascular injury. Stents can be prepared by any of the methods well known in the pharmaceutical art. See, e.g., Fattori, R. and Piva, T., “Drug-Eluting Stents in Vascular Intervention,” Lancet, 2003, 361, 247-249; Morice, M. C., “A New Era in the Treatment of Coronary Disease?” European Heart Journal, 2003, 24, 209-211; and Toutouzas, K. et al., “Sirolimus-Eluting Stents: A Review of Experimental and Clinical Findings,” Z. Kardiol., 2002, 91(3), 49-57. The stent may be fabricated from stainless steel or another bio-compatible metal, or it may be made of a bio-compatible polymer. The active compound may be linked to the stent surface, embedded and released from polymer materials coated on the stent, or surrounded by and released through a carrier which coats or spans the stent. The stent may be used to administer single or multiple active compounds to tissues adjacent to the stent.

Active compound as identified or designed by the methods described herein can be administered to individuals to treat disorders (prophylactically or therapeutically). In conjunction with such treatment, pharmacogenomics (i.e., the study of the relationship between an individual's genotype and that individual's response to a foreign compound or drug) may be considered. Differences in metabolism of therapeutics can lead to severe toxicity or therapeutic failure by altering the relation between dose and blood concentration of the pharmacologically active drug. Thus, a physician or clinician may consider applying knowledge obtained in relevant pharmacogenomics studies in determining whether to administer a drug as well as tailoring the dosage and/or therapeutic regimen of treatment with the drug.

In therapeutic use for treating, or combating, bacterial infections in mammals, the compounds or pharmaceutical compositions thereof will be administered orally, parenterally and/or topically at a dosage to obtain and maintain a concentration, that is, an amount, or blood-level or tissue level of active component in the animal undergoing treatment which will be anti-microbially effective. The term “effective amount” is understood to mean that the compound of the invention is present in or on the recipient in an amount sufficient to elicit biological activity, for example, anti-microbial activity, anti-fungal activity, anti-viral activity, anti-parasitic activity, anti-proliferative activity, anti-inflammatory activity or ameliorating a symptom of a gastrointestinal motility disorder. Generally, an effective amount of dosage of active component will be in the range of from about 0.1 to about 100, more preferably from about 1.0 to about 50 mg/kg of body weight/day. The amount administered will also likely depend on such variables as the type and extent of disease or indication to be treated, the overall health status of the particular patient, the relative biological efficacy of the compound delivered, the formulation of the drug, the presence and types of excipients in the formulation, and the route of administration. Also, it is to be understood that the initial dosage administered may be increased beyond the above upper level in order to rapidly achieve the desired blood-level or tissue level, or the initial dosage may be smaller than the optimum and the daily dosage may be progressively increased during the course of treatment depending on the particular situation. If desired, the daily dose may also be divided into multiple doses for administration, for example, 2-4 four times per day.

In light of the foregoing, the specific examples presented below are illustrative only and are not intended to limit the scope of the invention. Other generic and specific configurations will be apparent to those persons skilled in the art.

Synthesis of Tosylate 155

3-Butyn-1-ol (1.8 g, 25 mmol) was dissolved in methylene chloride (CH2Cl2) (40 mL) and triethylamine (Et3N) (4.18 mL, 30 mmol). The solution was stirred at 0° C. followed by addition of p-toluenesulfonyl chloride (5.05 g, 26.25 mmol). The reaction was allowed to warm to room temperature over a period of 1 hour and stirring was continued overnight. Thin layer chromatography (TLC) analysis (hexanes/ethyl acetate (EtOAc) 6:1) after 20 hours of reaction showed a complete consumption of 3-butyn-1-ol. The precipitated triethylamine hydrochloride was filtered off and the filtrate washed with water (H2O) (30 mL) and brine (30 mL). The organic layer was dried over sodium sulfate (Na2SO4) and the solvent evaporated away to give 155 as a light-yellow oil (5.45 g, 97%). The crude oil was used without further purification; however, it could be purified on a silica gel column, first eluting with 8% EtOAc in hexanes followed by 40% EtOAc in hexanes.

Synthesis of Alkyne 157

A suspension of O-tosyl-3-butyn-1-ol (2.8 g, 12.5 mmol), 2-methylaminoethanol (0.93 mL, 11.4 mmol) and sodium bicarbonate (NaHCO3) was heated at 50° C. for 20 hours. NaHCO3 was filtered, the solvent was evaporated, and the resulting residue was partitioned between H2O (30 mL) and EtOAc (30 mL). The layers were separated and the aqueous layer was back extracted with EtOAc (4×20 mL). The combined organic layer was dried over Na2SO4 and the solvent evaporated away to give an oil), residue. The oily crude was purified on silica gel column eluting with 5:1 CH2Cl2/methanol (MeOH) to give compound 157 as an oil (0.54 g, 37%).
